Problem: Field Calculation seems to run forever and clicking the Cancel button does not stop the process
When performing a field calculation in ArcMap on a dBASE table or a shapefile attribute table, the progress bar stays up and the calculation doesn't complete. Clicking cancel does not stop the calculation.
This is a known issue. The .dbf file has read only permissions.
Solution or Workaround
This issue has been resolved in ArcGIS Version 8.1.2.
In ArcGIS 8.1:
- Use the Windows Task Manager to end the ArcMap session.
- Make sure you have write permission to the table before attempting to calculate the values again.
- Restart ArcMap and calculate the values again.
